While I have described the details of construction of rnv invention, it is to be .clearly understood that my invention .isinot limited' to' these detailsof construcion, but is capable of other adaptations -and/ modifications within' the scope of the appended claims.

aying thus described my invention, what I desire to secure by Letters Patent of the- United States is:

r vehicle lamp comprising a housing,v

a shallow reflector with a longfocal length secured therein, its axis being inclined slightly downwardly from the axisof the housing, a light source mounted substantially at the focalr point of the reflector, an'outward'ly projecting light emitting closure to inclose the'lightsource, the relative positioningr of the reflector, housing andjlight source being such that the-light source is in advanceV of the housing and a concentrated beam is projected forwardly and slightly downwardly therefrom and direct rays -are released to illuminate an area forwardly and rearwardl therefrom.

2. l vehicle lamp comprising a housing, a reflector of a long `focal length secured therein, the` axis of said reflector being slightly inclined,'a light soiirce mounted in the axis of-.the reflector and projecting beyondthe' forward periphery of thehousing, and an outwardly` proJccl ing light emitting closure iiclosing the light source; so that a concen- .trated beam of'light is projected forwardly' and slightly downwardly. and direct rays from the source issue forwardly, upwardly, downwardly, laterally 'and slightly rearwardly.

3. A' vehicle lamp comprising a'hoiisingy a shallow reflector with a long focal length secured therein, its axis being inclined slightly downwardly from fhosubstantial horizontal axis of the housing, a light source mounted vsubstantially near the focus of the reflector, an outwardly projecting light emitting closure to inclose the light source, the

arward y, radially, andfor-l relative positioning of the reflector and light source in ythe liousinggbeing such that `the light source projects beyond the forward periphery of the housing.

4. A construction as defined 'in claim 1 in which the light emitting closure is provided with a central dillusingarea.

5.- AV headlight .comprising a concave reflector, the focus of which lies outside the` plane of lthe edge of said reflector, a single source of light located substantially at said focus, andan' outwardly' bulgingtransparent closure for said reflector havingr its margin extending at a substantial angle to the lateral rays of said light source, Said source otlight being positioned within' said closure, whereby a forwardly directed beam is produced and direct illumination laterally of the headlight is obtained.

G. A headlight comprising a shallow conlcave reflector. asingle source of light lying' outside of the-plane ofthe edge of said re- Hector and located substantially in the focus g of the lattei", and a transparent closure for said refiectorhaving marginal portions extending at :ui-angle to said plane, the axis of said reflector' being inclined to the horir, aontal, whereby a 'forwardly directed beam is produced and direct illumination laterally i of the headlight is obtained.

7; A headlight comprising a reflector, a single source of light positioned in advance `of the plane of the edge of the reflector and located substantially in the focus of the. latter toproduce a forwardly directed, reflected beam and lateral illumination substantially at right angles to Said reflected beam,the

axis of said reflector being tilted for'depressing the beam to avoid glareand a transparent, bulging closure for said reflector having marginal portions extending at a substantial yangle tothe lateral rays from the light soiirce so as to permit said lateral illumination, a portion of the rim of said reflector v lyingv in `the rear of the plane of the edge of the reflector. l l 8. A headlight for motor vehicles comprising a source of light, a'transparent outwardf ly bulging closure receiving substantially all lthe laterally emitted light from said-source and transmitting it in' a direction substantiallv at right'angles `t`o the axis of the headlight, and a shallow. concave reflector positioned in relation to the sourceof light so as to reflect a' concentrated beam of light through said closure in a forward direction` said closure being positioned in advance of said reflector and having its marginal portion facinglthe file nrient of said source of v light. y In ,witness whereof, I hereunto subscribe my name, this 3rd day of September, 1924. f WALTER DARCY RYA N.
